Benefits of technology

The invention provides a better way to connect RF cable end connectors to coaxial cables. It uses an insulator made by embedded molding to secure the position of the central and outer conductor terminals, which are important parts of the connection. This makes it easier to fix the position of the terminals during manufacturing. The connection can be done quickly and easily, which helps to lower costs. Overall, this innovation solves a problem that has plagued the RF cable industry for a long time.

Problems solved by technology

In such a case, however, how to fix relative positions of the central conductor terminals and the outer conductor terminals is usually an issue needed to be addressed when fabricating the RF cable end connectors.
However, the soldering technique is not favorable for automatic processes, making fabrication costs of the FAKRA cable end connector jumpers not able to be reduced.
Besides the FAKRA connectors, other structural configurations of the RF cable end connectors also adopt the soldering technique for cable bonding, and thus their bonding with coaxial cables cannot be performed by fully automatic processes.
This similarly leads to high fabrication costs of the RF cable end connector jumpers.

first embodiment

[0028]In this embodiment, the internal terminal 1 includes an internal terminal body 11 and an insulator 12. The internal terminal body 11 includes a central conductor terminal part 111, an outer conductor terminal part 112 and a connection part 113. The central conductor terminal part 111 has a central conductor clamp 1111 for clamping the central conductor 21. As shown in FIG. 1, the central conductor clamp 1111 can be provided between the central conductor terminal part 111 and the connection part 113 but is not limited to this arrangement. Alternatively, for example, as shown in FIG. 13, the central conductor clamp 1111 may be extended to a middle portion of the connection part 113. The outer conductor terminal part 112 has an outer conductor clamp 1121, an outer insulation layer clamp 1122 and a casing terminal contact 1123. The outer conductor clamp 1121 is used for clamping the outer conductor 23. The outer insulation layer clamp 1122 is used for clamping the outer insulation...

second embodiment

[0032]This embodiment differs from the first embodiment primarily in that, the internal terminal of this embodiment has its internal terminal body 11 composed of two individual pieces: central conductor terminal part 111 and outer conductor terminal part 112. An insulator is formed outside the internal terminal body 11 by embedded molding and fixes relative positions of the central conductor terminal part 111 and the outer conductor terminal part 112, making the internal terminal have a composite structure integrated with the insulator. This thereby solves the problem of not able to fix relative positions of central conductor terminals and outer conductor terminals during fabrication of conventional RF cable end connectors. In this embodiment, the central conductor terminal part 111 and the outer conductor terminal part 112 can be two separate metallic parts. Thus, the connection method of the RF cable end connector and the coaxial cable in this embodiment does not require step S12 ...

third embodiment

[0033]This embodiment differs from the first embodiment primarily in that, the internal terminal body of this embodiment has its central conductor terminal part and outer conductor terminal part being electrically contacted with the central conductor and the outer conductor of the coaxial cable respectively by a bonding technique such as crimping, soldering or ICD but excluding clamping. The connection method of the RF cable end connector and the coaxial cable in this embodiment thus as shown in FIG. 12 first executes step S21 in which when the central conductor and the outer conductor of the coaxial cable are placed within the insulator, they are bonded to the central conductor terminal part and the outer conductor terminal part of the internal terminal body respectively. Then step S22 is executed to provide the casing terminal and fix it on the insulator to cover a contact portion of the central conductor, and electrically contact the casing terminal with the casing terminal conta...

Abstract

A connection method of an RF cable end connector and a coaxial cable and an internal terminal used thereof are provided. An insulator is formed outside a body of the internal terminal by embedded molding, making the internal terminal have a composite structure integrated with the insulator. The internal terminal can be connected to the coaxial cable by, for example, clamping. This allows connection between the RF cable end connector and the coaxial cable to be easily accomplished by automatic processes, thereby reducing fabrication costs of RF cable end connector jumpers.
